1. A timepiece with a timepiece movement by which at least an hour display can be driven, the timepiece comprising:
a central pivot (2); a central disk (1) drivable so as to be rotatable in a clockwise or counterclockwise direction around the central pivot (2) by one revolution per 24 hours and on the surface of which is depicted the southern hemisphere or northern hemisphere of the earth or the degrees of longitude thereof, wherein the central pivot (2) passes through the pole (3) of the northern or southern hemisphere; a stationary 24-hour scale (5) arranged concentric to the central pivot (2); a sun mark arranged in a stationary manner in a 1200 hours position of the 24-hour scale (5) at a radial distance from the central pivot (2); a large moon disk (4), the central disk (1) being surrounded concentrically radially inside of the 24-hour scale (5) by the large moon disk (4), the large moon disk (4) being rotatably drivable in the counterclockwise direction at a rate of one revolution per synodic month; a moon view aperture (9) in the large moon disk (4); and a small moon disk (10) mounted at the large moon disk (4) so as to be rotatable around a moon pivot (11) parallel to the central pivot (2), the small moon disk (10) carrying a plurality of dark circular areas (12), corresponding to the moon view aperture (9), which are uniformly distributed on a pitch circle, the small moon disk (10) being rotatably drivable in a ratio to the rotational movement of the large moon disk (4), wherein the dark circular areas (12) are movable successively into registration with the moon view aperture (9) and successively out of registration with the moon view aperture (9) by the rotational movement of the small moon disk (10). |
